Wegovy 2.4mg injection features semaglutide, a GLP-1 receptor activator employed in the long-term management of one’s weight. It has been presented here as Wegovy flexpen, which is a ready-to-administer pen and is a weekly subcutaneous administration pen product and contains the pre-filled pen along with 4 single use needles only for one time usage.
Unlike several of the semaglutide brands we’ve covered, Wegovy is registered in Australia. The TGA lists Wegovy FlexTouch 2.4mg as an ARTG-registered medicine, and Healthdirect provides Australian product information for the 2.4mg presentation.
What Is Wegovy 2.4mg Used For?
Wegovy dosage of 2.4mg is prescribed to patients along with an overall lifestyle change programme (weight and food-related), which involves the combination of a restricted-calorie diet and more daily exercise.
Australian prescribing guidelines endorse the use of Wegovy for chronic weight management, for adults, when:
- There is a Body mass index of 30 kg/m² or above, or
- A body mass index from 27 kg/m² up to less than 30 kg/m² and it has been combined with a major weight-related disorder.
Not only does this lead to weight loss but also it helps with long-term weight maintenance.
In Australia, Wegovy can only be obtained with a prescription.
How Does Wegovy 2.4mg Work?
Semaglutide works by stimulation of GLP-1 receptors that participate in the regulation of appetite and diet.
The drug can have an impact on:
- Enhance the sense of fullness
- Diminish the desire for food
- Cut down on the desire to eat snacks
- Assist in managing the amount eaten
- Certain foods can lower overall energy intake
- Delaying the stomach’s emptiest
As a result, it can help people stick to a calorie-restricted diet. Semaglutide is not any kind of amphetamine or typical weight-loss pill through fat-burning. Instead, the weight-control effect of the medicine is mainly connected to its effect on hunger, satiety and diet intake changes
How To Use Wegovy 2.4mg
Wegovy 2.4mg is administered once weekly by subcutaneous injection.
It can be injected under the skin of the:
- Abdomen
- Thigh
- Upper arm
The injection can generally be taken at any time of day and with or without food.
You should avoid giving a shot directly into your vein or under the skin. A FlexTouch device needs to be inserted just under the skin with the help of the needle in the pen. After that, you can remove the safety cap or plunger and click the device to inject. If you are wondering what injection means, it refers to a shot. If you inject a drug like Wegovy with a needle directly into the bloodstream, there are certain risks like blood pressure issues or rapid heartbeat.
Wegovy 2.4mg Dosage
For weight management, semaglutide is gradually increased rather than starting immediately at 2.4mg. The usual escalation schedule is:
| Treatment period | Weekly dose |
| Weeks 1–4 | 0.25mg |
| Weeks 5–8 | 0.5mg |
| Weeks 9–12 | 1mg |
| Weeks 13–16 | 1.7mg |
| Maintenance | 2.4mg |
2.4mg is the maintenance dosage for adults if tolerated. It is generally recommended to gradually increase the dose so the body can slowly adjust to the treatment which in turn can diminish gastrointestinal side effects.
If 2.4mg leads to intolerable side effects, maybe your healthcare professional can prescribe you the lower dosage for a period of time before trying to go back to the higher dosage.
Do not start directly with 2.4mg unless specifically instructed by your prescriber.
What If You Miss a Wegovy Dose?
If a weekly dose is missed, the action depends on how long it has been since the scheduled injection.
If one dose of Wegovy is missed, it’s still okay to take it in the next 5 days. After that, the drug should just be used as usual for the next appointment, and the missed one would be the only one left. There is no point in doing more injections if the medicine has already been missed to catch up.
In the case of missing more than one dose of Wegovy, it’s recommended that a person discusses the matter with her/his doctor before starting the medication to ensure that the right dose has been decided (for example, the dose could be reduced).
Possible Side Effects
The most common side effects of Wegovy are gastrointestinal and may be more noticeable when treatment is started or the dose is increased.
Possible side effects include:
- Nausea
- Vomiting
- Diarrhoea
- Constipation
- Abdominal pain
- Headache
- Tiredness
- Dizziness
- Bloating or indigestion
- Injection-site reactions
Many digestive symptoms become less troublesome as the body adjusts to treatment.
Seek medical attention if you develop severe or persistent abdominal pain, particularly if it extends toward the back.
Repeated vomiting or diarrhoea can also cause dehydration and may affect kidney function.
Precautions Before Using Wegovy 2.4mg
Tell your doctor before using Wegovy if you have:
- A history of pancreatitis
- Severe gastrointestinal disease or delayed stomach emptying
- Kidney problems
- Gallbladder problems
- Diabetic retinopathy
- A history of serious allergic reactions to semaglutide
- A personal or family history of medullary thyroid carcinoma or MEN 2
- A planned operation or procedure involving general anaesthesia or deep sedation
Wegovy is not intended and should never be a choice for pregnant or planning pregnancy patients to lose weight. You had better consult your treating physician first whether pregnancy or not.
A side effect of semaglutide is delayed gastric emptying which could be a reason for gastrointestinal symptoms. According
to TGA, patients on GLP-1 therapy should inform their healthcare professionals (e, g. surgeons) that they are receiving that type of medication in order to prepare a safe plan during/after surgery/procedures.
Healthdirect has also mentioned the present TGA warnings about GLP-1 drugs and the risk of suicidal thoughts and suicide attempts. It is very important that if you experience any mental or behavioural changes you contact a healthcare professional at the earliest possible moment.
Wegovy 2.4mg and Other Medicines
Discuss with your doctor all medications, diabetes treatments, dietary supplements and weight-loss products that you currently take or use.
It is likely that additional care is needed if semaglutide is used together with insulin or sulfonylureas because the combination might raise your chance of experiencing low blood sugar.
Mind that since the mechanism behind a delay of gastric emptying by semaglutide also affects your body’s ability to absorb oral medications, there may be changes to the way certain drugs are processed.
In most cases, you should not use Wegovy and another GLP-1 receptor agonist together that contains semaglutide unless it is explicitly recommended by your healthcare provider.
